First put everything into the same measurements.
111 km = 111km
42mpg = 67.592kpg
1 U.K. Gallon = 4.546 liters
67.592/4.546 = 14.8684557853
42mpg = 14.87kpl (kilometers per liter)
1.10 euros/liter = 1.10 euros/liter
If you drive 111 km a day and go 14.87 km a liter, divide 111 by 14.87 to get about 7.46, which is how many liters you will use a day. Multiply the price, 1.10 euros, by the number of liters, 7.46, to get the daily price of gas, which is about 8.206 a day. Multiply by 7 (num of days in week) to get about 57.44
It cost about 57.44 euros for one week of gas.
I hope I'm not too late! And hopefully that is right! No guarantees lol
Answer:
Alpha particle or helium nuclei.
Explanation:
Alpha particle:
Alpha particle is emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
Answer:
Carbon monoxide
Explanation:
Carbon dioxide and carbon monoxide have the same number of carbon atoms.

The formula used for determining gas pressure, volume and temperature interaction would be PV=nRT.
<span>• What is the temperature in Kelvins?
</span>You already right at this part. Kelvin temperature formula from celsius should be:
K= C+273.15=
<span>K= 27 +273.15 = 300.15
It is important to remember that the formula in this question is using Kelvin unit at temperature, not Celcius or Fahrenheit.
</span>
<span>• Assuming that everything else remains constant, what will happen to the pressure if the temperature decreases to -15 ºC?
</span>In this case, the temperature is decreased from 27C into -15C and you asked the change in the pressure.
Using PV=nRT formula, you can derive that the temperature will be directly related to pressure. If the temperature decreased, the pressure will be decreased too.
<span> If you increase the number of moles to 6 moles, increase temperature to 400K and reduce the volume to 25 L, what will the new pressure be?
</span>PV=nRT
P= nRT/V
P= 6 moles* <span>0.0821 L*atm/(mol*K) * 400K/25L= 7.8816 atm</span>
Increases. It gets harder to breathe and keep the rhythm.
